The conversion is for the majority of the conversion processes the value means for the special connections comprise the average occupancy time of the corrector in this known arrangement "conversion sub-arrangement compared to the previously known correcting stages, each of which is one of the η groups reduced from arrangement. In addition, needs when inferences is assigned. The group identity of one of these corrector arrangement at the same time only special connection results exclusively from one of the η sub-levels of the first corrector level and from the group number part of its call number. possibly thereafter the only second sub-level This means that each revaluation sub-level contains both 20 to be occupied, regardless of whether item numbers whose group part is omitted is a revaluation from call number to item number, since it is associated with the identity of the revaluation sub-level or from item number in Call number occurs, matches, as well as complete position numbers.

Before going into the description of the drawings in more detail, the symbols used should be explained. So are ferrite core memory such. B. M 1 in FIG. 1, represented by rectangles and denoted by the letter M with indices; the vertical and horizontal lines arranged in a rectangle represent the columns and rows of the matrix memory.

The ferrite cores with a rectangular hysteresis loop (e.g. in the memory M ₂ 'in Fig. 2) are represented by short diagonal lines, where () means a core set in its 1 state and (\) a core set in its 0 state.

The access devices assigned to the memories (for example AC1 in FIG. 1) are represented by triangles. The tip marked with an arrow corresponds to the inputs, the edge opposite this tip corresponds to the outputs.

OR gates (e.g. 02 in Fig. 2) are shown as small circles with a cross inside. An OR gate (e.g. O 4 in Fig. 9) surrounded by a right !: drawn with dashed lines represents a set of OR gates.

Invertors (z. B. / 1 in F i g. 2) are shown as small circles with two mutually perpendicular, inclined by 45 ^C diameters.

A flip-flop, such as FQ in Fig. 1, is represented by two rectangles arranged one above the other with the designations 1 and 0. The I and O inputs (or outputs) are shown as arrows pointing to (and from) the lead accordingly labeled rectangles. Flipfiops are usually in the 0 state, in which only the O output is active.

Coincidence detectors or comparators, such as. B. CDI in Fig. 1, are shown as rectangles and denoted by the letters CD with indices. The input of a coincidence detector opposite the output is its control input.

An arrow ii shown with a dashed line in the direction of a bistable device indicates this Reset input.

The mode of operation of the double-directional corrector arrangement will first be described in connection with mi the forward conversion, d. H. the conversion before call numbers into position numbers, explained under reference to FIGS. 1 to 8. Then, using FIGS. 9 to 13, the reverse direction of the conversion, d. H. the conversion of position numbers into phone numbers is explained.

In the exemplary embodiment shown, it is a matter of a corrector arrangement which is suitable for use in a telephone exchange with sixteen subscriber groups, each of which comprises a maximum of 2 ™ = 1024 partial line connections. However, a maximum of 1000 call

ao numbers assigned. The excess of 24 connections is not wasted because it is z. B. for Hunt groups can be used. In order to simplify the description, it is assumed that that each of the sixteen groups comprises 1000 subscriber lines.

The subscriber numbers consist of six-digit decimal numbers in the form ADMCDU. The ABM part of a call number normally indicates the group, while the CDU part indicates the rank

designated within a group. The call numbers are coded in decimal binary form, with each decimal place A to U being represented by a 4-bit binary digit.

The position numbers consist of 14-bit binary numbers in the form i / 3 i / 2 £ / 1 U0X9XS ... XO. The part U3 ... UO of a position number represents the group number part that designates the frame to which the subscriber line concerned is connected. Part X 9 ... AO identifies the special subscriber circuit that is assigned to the subscriber line concerned in the frame U3 ... UO.

A subscriber line is considered to be normally offset if it is only offset within its group of thousands, that is, if the ABM part of the call number and the U3 ... UO part of the position Hummer are related to one another by a predetermined, fixed conversion rule given is; the parts CDU and X9 ... AO are not related to one another in this way. The

indicates that such a line, which should normally be connected to the subscriber circuit defined by the call number part CDU , is offset in the frame concerned, within this frame and connected to another subscriber circuit defined by X 9 ... XO.

A subscriber line, for which the fixed relationship between the parts ABM and U3 .. .UO does not apply, is also offset with respect to the group or the frame. This means that a line that should normally be connected in the frame defined by ABM is connected in a frame defined by the item number part i / 3 ... i / 0. It is then a particularly staggered subscriber line.

ög From the above it follows that a subscriber line for the position and call number are completely in the fixed, predetermined relationship to one another, at all is not offset From the above it also follows that

^ ^{> ι} Ί 9

of the lines of a hunt group that all have only one call number in common, at most only a line cannot be offset.

The subscriber lines of an exchange are divided into normal and special connections.

A connection is normal if it meets the following three conditions:

It is connected, it is not moved, and it has normal identifiers (incoming and outgoing).

A connection is considered a special connection if at least one of the following conditions applies to it is applicable:

Not connected, offset, special identifiers (outgoing or incoming).

The special connections are also in first order special connections and special Second order connections divided. The particular first-order connections include those within connections offset in their group (normally offset connections) as well as non-offset connections, which have special identifiers. The special second order connections include those outside their group staggered connections (especially staggered connections). Accordingly, the corrector arrangement comprises two stages: a first-order corrector stage with 16 sub-stages, the special Connections of the first order of the 16 groups are assigned, as well as a corrector stage of the second order, which is assigned jointly to all special connections of the second order of the 16 groups.

The mode of operation of the corrector arrangement is as follows:

A connection line for which a correction is requested is initially regarded as a normal line. Your phone number (position number) is based on the fixed, specified conversion rule converted into the corresponding position number (phone number). The position number calculated in this way (Phone number) is used to address a detector for special connections. If it is determined to be a special port, it is initially assumed that it is a special first-order connection. Hence, that of the affected Sub-level of the first-order corrector level assigned to a group of thousands is used for correcting the value. If this evaluation process has no result, it can be assumed that the connection is a special one Connection of the second order is, and the corrector stage of the second order is used for the conversion used.

Of course, the corrector does not need a converted number for lines that are not connected to provide only the statement about this condition. In the present case, this statement is obtained indirectly due to the missing result of the revaluation of both corrector levels. This can e.g. B. enter, if a number that is not connected is dialed by incorrectly dialing.

In the corrector arrangement according to FIG. 1 a call number ABMCDU to be converted is received and saved in the REO register of the IRC input circuit. Then the flip-flop FO, which is assigned to the conversion of call numbers, is brought into its 1 state. The activated! Output / 0 of the flip-flop FO makes the AND gates GO and Gi conductive. The part ABM de: call number ABMCDU reaches an input of the coincidence detector CDI via the AND gate GO , and the clock pulse pending at the output h of a clock generator, not shown , reaches an incremental input of the scanner ADl via AND gates Gl. The scanner ADl consists of a four-stage binary counter that can take 16 counts from 0000 to 1111. Each count corresponds to a group number U3U2UIU0, which designates a frame and is assigned to one of the 16 groups mentioned.

ίο The access device ACl decodes each of the 4-bit codes U 3 U 2 UI UO supplied in succession by the scanner AD1 and sets a query signal in each case! to the corresponding memory line, that is to say to the line containing the number A BM which corresponds to the code number U3U2U1U0 supplied by the scanner. The information read in each case from the memory Ml replaces in the memory register RE I the information previously read from the memory Ml. If the number ABM read from a line of the memory M1 into the register RE1 is identical to the part ABM of the call number ABMCDU contained in the register REO , the coincidence detector CDI responds and switches the flip-flop F1 to the 1 state. The no longer active 0 output of the

Flip-flops Fl blocks the AND gate Gl for clock pulses, and therefore the scanner ADl stops . The active 1 output of the flip-flop Fl controls the AND gates G 2 and G 3 to be conductive. About AND gates G 2 reaches the count i / 3 ... LO of the scanner ADI in the register RE 2, and AND gates G3 reaches the part CDU dialing ABMCDU contained in the register in the register REO REI after this part CDU was brought into binary form X 9 ... X 0 in the code converter CCl . In this way, stored in register REO number ABMCDU U0X9 AO was in its corresponding, stored in the register REI position number U3 ... ... converted. This number, obtained through revaluation, corresponds to the call number

is now used to address the memory part MJ of the memory M 2 of the detector for special connections. The memory M2 contains 16 memory parts ₂ M ¹ ... M _a ^Ifi, each one of the 16 groups of 1000 is assigned to terminals. Everyone

Memory part MJ (J 1 to 16) contains 16 columns (/ - ■ 1 to 16) and 64 rows (j 1 to 64), and each of its crossing points is assigned to a terminal of the / -th group of terminals.

As can be seen from Fig. 2, the decoder decodes

309 542/199

which are connected to the outputs of the AND gates GS, G 6 of the 16 column gate circuits GCl ... GC 16.

If the ferrile core is in the O-state at the selected crossing point of the storage line Mj, this means that the associated connection is normal. In this case, the output signal of the ferrite core concerned causes the flip-flop F1 to be toggled into its! State, as a result of which the AND gates Gl are controlled to be conductive. The position number U 3 corresponding to the call number arrives via the AND gates Gl. . . UO, X 9. . . XO, which represents the position number you are looking for, into the ORC output register. The conversion is thus ended, and the output register ORC brings the corrector back to the rest position via its output rst.

However, if the ferrite core of the selected crossing point of the memory part MJ is in the 1 state, this means that the associated connection is a special connection. In this case, reading the ferrite core causes flip-flop F3 to be toggled into the 1 state. As has already been explained, it is initially assumed that it is a special first-order connection, and therefore the relevant sub-stage of the first-order corrector stage assigned to these connections (FIG. 3) is used to carry out the conversion. This first-order corrector stage comprises a memory M 3 which comprises 16 memory parts MJ (i = 1 to 16) which form the 16 sub-stages which are assigned to the 16 groups of 1000 connections each. Each memory part MJ contains 16 columns and a suitable number of rows.

Fig. 4 shows schematically how information is stored in the memory part MJ. One of the η memory cells a1 to an of the memory part MJ is assigned to each special connection of the first order or hunt group within the / th group of thousands. The number of words per memory cell is variable and depends on the identifiers or performance features of the connection or the hunt group. Each word contains certain information, such as call number DN, position number EN, identifier CL or relative address RAM for another memory, as well as a code (index) which identifies the type of information. The first word in a memory cell always contains the call number DN of the connection concerned as well as the information "hunt group" or "no hunt group". In the case of a Sainmel connection, the first word contains the common hunt group number DNG.

For single connections, the following words contain the position number EN if it is an offset connection (ie if DN ψ EN), and the identifiers if the connection is assigned special identifiers.

For a hunt group, the words following the hunt group number DNG contain one after the other

the position number ENO of the first hunt group line if it is different from the hunt group number DNG, and

a password CLO for the first hunt group line, if required; for other lines of the hunt group:
the position number and
the respective password, if required.

The call and position numbers are 10-bit binary numbers that occupy bits 7 to 16 of the memory lines concerned. Each of these 10-bit numbers defines the connection assigned to it within the affected group of thousands. In other words: A call number DN is represented by its part CDU in direct binary coding, i. h by the part ΛΓ9 ... ΛΓ0 of the position number corresponding to this number: A real posi

ίο tion number EN is represented by its part X 9 ... XO. The group parts ABM or U 2, ... Ui of the call and position numbers are omitted because they match the address dt ν of the respective memory part M _x (i = 1 to 16).

An identification word CL contains 13 bits which occupy bit positions 4 to 16 of the memory lines assigned to them, as well as a 3-bit index (code 110) which identifies this type of information. For connections with extensive identifiers and / or other specifications for performance features (e.g. visiting service) that require more than one memory line, the line following the position number contains a relative RAM address (bit positions 4 to 14) of the first word instead of an identification word Storage cell of a memory MS (in Fig. 7) of an auxiliary corrector which contains the desired information. Bits 1 to 3 of the above-mentioned line of memory line MJ contain a 3-bit index (code 111) which identifies this type of information, while bits 15 and 16 contain temporary identifiers, e.g. B. specify whether a visit switching is activated or not, etc.

In the case of a hunt group which includes both offset lines within their groups and lines offset outside their groups of thousands, the last word of the assigned memory cell in the memory part MJ contains the relative address RA M 4 of the first position number in the memory cell of the memory M4 of the second order corrector that contains the information for the special second-order connections of the hunt group.

In Fig. 4, the memory cell al of the memory

Assigned hunt group, which includes special lines of the first and second order. The last word of the memory cell on contains a relative address RAM 4 for the purpose of connection to a corresponding memory cell (cell a'm in FIG. 6) of the memory

chers MA of the second order corrector. Memory cell an is assigned to a collective connection having only special lines of the first order. F i g. 6 shows schematically how information in the memory M 4 of the second order corrector is

stores are. The organization of this memory, which is jointly assigned to all special connections of the second order of all 16 thousand groups, is similar to the organization of a memory part MJ with

1 q

the exception that the phone and position numbers are stored here in their entirety. The call numbers DN are stored in direct binary code by means of bits 3 to 16 of the respective lines, i.e. left, they are given by the corresponding item numbers U3 ... U0, X9 ... X0. Bits 1 and 2 of a line containing a call number or position number represent an index that indicates whether it is a call number (code 00) or a position number (code 10). Cell b \ '° of the memory MA is assigned to a special individual connection of the second order, which has special identifiers. Cell dm is assigned to the special lines of the second order of that hunt group whose special lines »5 of the first order are served by the cell on of the memory part M _s '. It is worth mentioning that in the memory cell on the hunt group call number DNG is repeated in its complete form in the first row of the memory cell.

F i g. 8 shows schematically how the information is stored in the memory M 5 of the auxiliary corrector. The memory cells of this memory M 5 contain 16-bit lines, the number of which is variable and depends on the particularities of the connection assigned in each case. Bits 1 to 3 of the first row of each memory cell contain an index which indicates the type of information stored in the memory cell. Bits 4 to 14 of the first line are identification bits, while bit 16 indicates whether the first password word is followed by another. The values of bits 1 to 3 and 16 of the described first line (code word) of a memory cell of memory M 5 are:

35

Bit 1: always "1";
Bit 2: »1« for speed dial authorization,

»0« if there is no speed dial authorization;

Bit 3: "1" for authorization to visit

switching,

»0« if you do not have authorization to
Visit switching;
Bit 16: "1" if a second password word

follows,

"0" if there is no second password
follows.

In the present exemplary embodiment, it is assumed that the abbreviated dialing numbers are two-digit decimal numbers KL . The abbreviated dialing numbers KL are stored in the decimal binary code in the bit positions 9 to 16 of the assigned memory lines. Bits 1 to 8 of these lines contain an index (code 11 000 000) which identifies this type of information. The complete numbers comprising twelve decimal digits N 12 ... N 1 are also decimal binary coded and follow the assigned speed dial numbers.

In the part of the memory M5 shown in FIG. 8, the memory cell el contains two password words CL 1 and CL 2, and the connection is not authorized for either abbreviated dialing or visiting switching. Cell el is assigned to a connection that is authorized to switch visits. Cell d contains an identification word and the number TR of the subscriber line to dsm the incoming connections are to be diverted when bits 15 and 16 in the relative address word of the assigned memory cell of memory M 3 or memory M 4 indicate that the visitor's sound is activated. The number TR comprises eight decimal digits Pi P2 ABMCDU in decimal binary coded form. P1P2 represent the area code, ABMCDU the call number. Memory cell c3 is assigned to a connection which has extensive identifiers and is authorized for speed dialing. The cell comprises two password words CL 1 and CL 2 and two abbreviated dialing information items ABBl, ABBl, which contain the abbreviated dialing numbers KL and K ¹ L ', followed by the assigned call numbers NU ... / Vl and ΝΊ2 ... N'l .

Returning to FIG. 2, the case is now considered in which flip-flop F 3 was toggled into its 1 state, as a result of the query of the ferrite core of a special connection whose position number corresponding to the call number is stored in register RE2. The active 1 output / 3 of the flip-flop F3 controls on the one hand the AND gate G ₈ 'conductive, the second input of which is connected to the output / of the decoder DECl , and on the other hand the output / 3 controls the logical network LNWl (Fig. 3) that is assigned to the memory M3 of the first-order corrector. The output gi of the conductive AND gate GJ makes the AND gates G 9 (FIG. 3) conductive, which belong to the memory part M., ⁽ which is assigned to the special connections of the first order of the / th group of thousands active output vv8 of the logical network LNWl controls the AND gate GlS (Fig. 3) conductive, via which clock pulses from the output h of the clock to the stepping input of the scanner AD2 . The scanner AD2 is all memory parts MJ to M., ^{1 (i} des Memory M 3 jointly assigned and when the clock pulses are supplied, the scanning of the memory part M ₃ ″ via the conductive AND gates G 9. The results of the successive reading of the individual lines are stored in the register RE 3 by overwriting the information previously stored. The logical network LNWl checks the code (index) which identifies the type of information of each word contained in the register RE 3. The output w 7 of the logical network LNWl is always active when we nn in register RE3 (Fig. 3) a phone number DN is displayed. For the time in which the output w 7 is active, the coincidence detector CD 2 is activated and compares the parts X 9 ... XO of the numbers stored in binary form in the registers RE2 and RE 3. If part X9 ... XQ of a call number stored in stages 7 to 16 of register RE 3 is the same as the homologous part of a call number stored in register RE1 , the coincidence detector CD 2 responds and communicates the coincidence to the logical network LNW1 .

If the code in levels 1 to 6 of the register RE3 indicates that the call number DN belongs to a single connection and is equal to the position number (e.g. in the case of the connection to which the memory cell a 1 in FIG. 4 is assigned ), the output w I of the logical network LNWl is conductive and controls the AND gates GlO, GIl conductive. Via this, the group part i / 3 ... I / O from the register REt and the part X9 ... XQ from the register RE3 go from the desired position number to the output register OR C. The query of the next line of the memory cell al under consideration causes this
